Wow, that's amazing that it can detect light from objects at 200K. That's about the temperature of dry ice.

- Roboprog 6y agoFor anyone missing how little radiation that is, radiation is proportional to the 4th power of the temperature in Kelvin. 200 K is a bit below (water) freezing. 400 K is just over boiling. The 400 K object emits 16 times (2 ^ 4) more radiation than the same object at 200 K.
